 PWF scales can only have odd numbers of notes.
-A signature, i.e., a generalisation of a MOS signature, can be used to uniquely define a an equivalence class of PWF scales equivalent under mirror-inversion and rotation, i.e., a chiral scale pair, or an achiral scale.

 '''Conjecture''': The GO scales of odd cardinality are the PWF scales that are not '''''abacaba'''''.
